PITTSBURGH, PA --

Pittsburgh's chief prosecutor says the armored car guard who spent nearly two months on the run after stealing more than $2 million from his truck admitted killing a fellow guard but claimed he fired in self-defense.

Allegheny County District Attorney Stephen Zappala tells the Pittsburgh Tribune-Review that Ken Konias Jr. claimed his partner tried to stop him from pulling off the heist.

Konias was arrested Wednesday in Pompano Beach, Fla., eight weeks after he allegedly shot fellow Garda Cash Logistics guard Michael Haines in the back of the head before swiping an estimated $2.3 million and leaving their truck parked under a Pittsburgh bridge.

Pittsburgh police say Konias' run came to an end after he confided his crimes to a prostitute.
